GATA3 and infection: In accordance with earlier work demonstrating the dependence of granuloma formation on type-2 cytokines12, we found that cells isolated from the small intestine of BALB/c mice on day 7 post-infection comprised significantly higher frequencies of GATA-3+ Th2 cells, both expressed as a percentage of CD4+ and total live cells, as well as higher frequencies of eosinophils (Fig. 1B, C).
